Some people naturally have higher levels of proteins that protect them from covid-19. New studies at Umeå University of our immune system may pave the way for more personalised treatments of both covid-19 and autoimmune disorders.
Researchers at Umeå University and Tartu University have found that a history of repeated antibiotic use causes defects in the normally protective mucus barrier of the gut, due to antibiotic-driven alterations in the microbiota. In a further study in a different collaboration, the researchers found a bacteria-independent mechanism through which antibiotics can damage the mucus barrier directly.
A variety of potentially disease-causing bacteria exist in the Baltic Sea and in Swedish lakes. Karolina Eriksson, a doctoral student at the Industrial Doctoral School at Umeå University, reveals in her thesis future health risks for humans in the light of climate change.
The dreaded tick-borne encephalitis (TBE) virus infects different types of brain cells in different parts of the brain, depending on whether the affected person's immune system is activated or not. This is shown in a new study at Umeå University, Sweden.
Umeå University researchers have participated in an international collaboration that has revealed the molecular structure and mechanism in the formation of a special and previously unknown type of zigzag-shaped pili structure that is found on the bacterium Acinetobacter baumannii. The new findings are published in the journal Nature.
Why does chronic stress lead to increased risk for dementia? The answer may lie in the elevation of stress steroids that is seen in the brain during stress, Sara K. Bengtsson suggests in the thesis she is defending at Umeå University on March 22nd.
High blood levels of Vitamin D may protect mothers more than babies against multiple sclerosis (MS), Umeå University researcher Jonatan Salzer concludes in Neurology, the medical journal of the American Academy of Neurology.
